Feel a jerk when accelerated from a complete stop stop and have this code
Transmission System: P0873.
Did a quick search online and pointed to transmission pressure switch. But which one? I have 2011 MDX.

Immediate question is it safe for the transmission while driving temporarily with this issue. Of course I need to get it fix ASAP.


Who can tell me which automati transmission pressure switch below for which gear from this diagram


Thanks

based on the code P0873 , the SM said it’s the 4th clutch pressure switch:

No! Front of the trans. Look closely at the picture that was posted.
